Niarchos: Pillar of the Warhol Market?

The Master, Judd Tully, reports on speculation about who bought the Warhol 200 One Dollar Bills earlier this week:

one New York–based trade source close to the Warhol market said the rarefied painting was bought on Wednesday evening by Greek shipping heir and world-class collector Philippe Niarchos, who is also believed to be the buyer behind the Warhol-record-setting $71.7 million sale of Green Car Crash at Christie’s New York in May 2007.
